BoombaRacing Focus RS Intake Manifold Spacer

$164.99

This spacer adds volume to the air entering your head. This has been shown to aide in cylinder filling at lower RPM, smooth out throttle response, build boost sooner, and lengthen the effective wave pulse of the intake charge. In the picture shown above, you can see the dyno charts of this spacer paired with our throttle body spacer and the gains are tremendous. Over 30 ft lbs of torque (in using both spacers) and a significant change in the horsepower curve.

The spacer also includes 8 1/8" NPT threaded ports that can be used for aftermarket injection set-ups such as Aquamist. They come with plugs for those just wanting to use the spacer on its own.
